Brock Lesnar made his expected return at a World Wrestling Entertainment (WWE) live event held at The Forum in Los Angeles and the unfortunate WWE star to welcome him back was U.S. champion Alberto Del Rio.

Well, technically it wasn't Del Rio alone but also Rusev. And as everyone knows, the two are members of the celebrated stable led by Sheamus, the "League of Nations," which means that when one is in trouble, the other/s come running.

As far as the live event is concerned, it was only Del Rio and Rusev in the picture, although it remains to be seen if this scene will develop into a storyline. Lesnar has no current storyline so it seems that a potential feud with the "League of Nations" could materialize.

If so, it begs to ask the question on whether or not Lesnar will play face once he returns to the WWE regular shows. While the possible angle has been mentioned before, it seems interesting how it will affect the ongoing conflict (per storylines) between Sheamus and WWE heavyweight champion Roman Reigns.

Taking it up a notch, one has to wonder if both angles would at some point be integrated. Lesnar and Reigns joining forces?

Well, such could be unlikely, but if one looks back at the history of the two stars, there doesn't seem to be any conflict between the two of them which dates back to Wrestlemania 31.

Even with the trio of Sheamus, Rusev, and Del Rio, one knows that the numbers game will practically be even with the two big forces bound together.

But in reality, it could be a rare combo, meaning it isn't expected to be a regular booking. In fact, if one looks beyond it, such could be a way to spark up a new rivalry between the two, with the WWE heavyweight title tied up to it.
